About This Manual
We recommend that you read and understand everything in this manual before setting up and using
the product. However, we recognize that users have different styles of learning: some will want to set
up and use their new emulator while they read about it; others will open these pages only as a “last
resort” to check on a particular specification. Therefore, we have designed this manual to be used
either as a “how to” procedural manual or a reference guide to important data.
Additional assistance is provided in the following ways:
■
The new emulator Graphical User Interface (GUI) software features many enhancements, including
an improved context-sensitive on-line help facility that provides brief messages on keyboard,
emulator commands and various procedures on how to use the emulator. (Refer to Chapter 1,
“Introduction” in this manual and the “README.TXT” file on the Z8 GUI diskette.)

5. Plug the white connector on the other end of the cable into the matching 4-pin connector on the
back or the left side of the ICEBOX™. (This connection is “keyed” to ensure against an improper
connection.)
Connecting the Serial Cable to the PC
Locate the serial cable. Connect the male end to the female connector on the back of the ICEBOX,
and the female end to either the COM1, COM2, COM3, or COM4 connector of your PC.
NOTE: If connector availability is limited to a 9-pin COM1 through COM4, you’ll have to use either a
different cable or a 25-pin to 9-pin converter. (Zilog does not provide either of these items.)
Connecting to Your Design
(Skip this paragraph if you your design is not ready yet.)
Locate the emulation cable for the device you’ve designed in.
NOTE: Wear a properly grounded wrist strap or similar ESD protection before continuing.
Plug one end of the ICEBOX emulation pod into your target MCU socket, being very careful to orient
the pin 1 marking (as indicated by the red mark on the ribbon cable) to match the pin 1 on your target
board. Plug the other end of the cable into the matching blue connector on top of the ICEBOX.

NOTES:
1. The emulation cable inductance and capacitance may affect the signals to and from the target
board, especially if the target board has low-current drivers, pull-ups, and pull-downs. We
recommend that you drive the XTAL pins of the device with the crystal oscillator on the
emulator with the J2 and J3 Jumpers removed.
2. It may be necessary to reconfigure the emulation cable with the appropriate target pod for your
target device package.
Connecting a Logic Analyzer (Optional)
Thelogicanalyzer can be connected as part of initial setup (or later as youcontinueworkingwith your
parts).
Connect the logic analyzer to P4 Connector of the Emulator.
NOTE: An ICEBOX emulator with a 100-pin connector requires a HP analyzer interface board (P/N
Z89C0000ZHP or ZINVASM0ZHP from Zilog).
Setting up the Oscillator and Option Jumpers
The oscillator and selected option jumpers are accessible from the top of the ICEBOX emulator (see
Figure 2-3). The option jumpers, which are accessible through the top cover, allow you to configure
things like whether the ICEBOX emulator provides power to your design on the V
cc
pin(s) of the em-
ulated device, and how the clock pin of the emulated device is connected. The clock for the emulated
device can be provided from an oscillator in the ICEBOX emulator or from a TTL-level clock on your
design. For electrical reasons, it cannot be provided from the oscillator on your design until you’re
done using the ICEBOX emulator and have done one of two things: 1) programmed an EPROM or
OTP device and installed it in your design, 2) installed a masked-ROM Z8 in your design.
NOTE: Each Z86K15 ICEBOX is shipped with a 8 MHz oscillator to emulate 4 MHz system clock. If
you want other rates, remove the oscillator and install a different one, within the frequency
specifications of the device in use. (Zilog, however, does not guarantee such operation.)

WARNING!
If your design already has a power supply, do not power your design from the ICEBOX™ emulator
V
CC
pin.
Powering Up
If anything unusual (such as unexpected sounds and smells) occurs the first time you turn on the pow-
er supply, quickly turn off the power supply and check your connections. If your power supply allows
voltage adjustment, adjust it again to +5V (It may be somewhat lower than +5V because of the load
oftheICEBOXemulator.)If your power supply has a currentmeter,ensurethattheICEBOX emulator
is drawing within the rated current.
Afterpower-up,presstheRESET button to reset the Z8 ICEchip.(PressingtheRESETbutton avoids
bus contention on the I/O lines.) If the ICEBOX emulator is not powering your design through the V
CC
pin, turn on the power supply of the design.
Powering Down
When powering down, follow the procedure described below:
1. Power down the target application board (if using its own power supply).
2. Power down the ICEBOX emulator.
(Refer to the complete “Electrical Safeguards” shown on the inside cover of this manual.)
EMULATOR OPERATION
Resetting
Pressing the RESET button on the ICEBOX emulator resets the state of the target device and much
of the status that you establish using the GUI. For example, it resets the emulated ROM size and
clears all Breakpoints. If your application board drives the /RESET pin of the device socket Low, the
target device is reset. For example, it sets the Program Counter to %000C, but does not affect most
of the other GUI and ICEBOX emulator status.
NOTE: After reset, you must wait until LED A is on (finishes blinking) before starting the GUI
software. (Refer to “LED Operation” section, which is later in this chapter.
WARNING!
You must always press the RESET button on the ICEBOX emulato
r before selecting the Z8-ICE
icon.

ST97KEY0100 2-11
ROM Size
The ICEBOX emulator features selectable ROM sizing.
Breakpoint Implementation.
The ICEBOX emulator bases its breakpoint facility completely on addresses, rather than on inserting
special “Trap” instructions into the program, which means you can set breakpoints in ROM on your
target board. The ICEBOX emulator uses a static RAM for each cycle emitted by the Z8 ICE chip dur-
ing code execution to implement the breakpoint function in hardware.
LED Operation
Stand-Alone Mode Operation
This emulator can be operated in a Stand-alone Mode. A fixed program is provided in a user EPROM
socket, and none of the terminal-based debugging facilities are available. Please follow these steps
to reconfigure the ICEBOX for Stand-alone Mode:
1. Power down and disconnect all cables from the ICEBOX.
2. Turn the ICEBOX upside-down and (using a small Philips screwdriver) unscrew the four screws
that hold the box together.
3. Remove the bottom of the case, leaving the black front and back panels with the rest of the
ICEBOX.
4. Carefully remove the daughterboard (the small, upper board) from the motherboard.
